The carbon–carbon double bond (pi or π bond) is the most reactive part of an alkene, but cannot rotate around its primary axis. This is a preview of subscription content, log in via an institution to check access. Author information Authors and Affiliations 2020 Howell Mill Road C227, ...
…EPDM is that the residual carbon-carbon double bond (i.e., the double bond that remains after polymerization) is attached to the polymer chain rather than being made part of it. Carbon-carbon double bonds are quite reactive. For example, ozone in the atmosphere adds quickly to a double ...
摘要: Double bonds activated by the electron withdrawing group(s) are cleaved with the reagent system consisting of a hard Lewis acid and ethanethiol to give dithioacetals.关键词: thio compounds (benzene compounds DOI: 10.1016/0040-4039(81)80019-6 ...
Regioselective vicinal diamination of carbon–carbon double bonds with two different amines is a synthetic challenge under transition metal-free conditions, especially for the synthesis of trifluoromethylated amines. However, the synthesis of ethylene di
Carbon, either elemental or combined, is usually determined quantitatively by conversion to carbon dioxide gas, which can then be absorbed by other chemicals to give either a weighable product or a solution with acidic properties that can be titrated. ...
control is convenient, repetition is easy, the activity of the catalyst is high, and reuse stability is good; the carbon-carbon double-bond hydrogenated iron carbide catalyst and the preparation method are suitable for industrial application to multiple kinds of carbon-carbon double-bond compound hyd...
To determine which carbon-carbon bond has the minimum bond length, we need to analyze the types of carbon-carbon bonds and their respective bond lengths. 1. Understanding Bond Types: - Carbon can form three types of bonds w
Besides the addition of an electrophilic species to a carbon–carbon double bond that was examined in the preceding section, an alternative way to create a carbocation is to remove one electron from the double bond. This can be achieved either by chemical means (strong oxidants, formation of ch...
Comparison of isoelectronic aluminum-nitrogen and silicon-carbon double bonds using valence bond methods In the reaction between trimethylaluminum and ammonia to form aluminum nitride, (CH3)2AlNH2 is a postulated intermediate. Results of ab initio geometry opt... MM Lynam,LV Interrante,CH Patterson...
Dative bonds between p- and d-block atoms are common but species containing a double dative bond, which donate two-electron pairs to the same acceptor, are far less common. The synthesis of complexes between UCl4 and carbodiphosphoranes (CDP), which form
